Summary
[edit]DescriptionHyalite opal (Spruce Pine, North Carolina, USA) (29637226160).jpg |
Hyalite opal on granite from North Carolina, USA. (public display, National Rockhound Hall of Fame, Murdo, South Dakota, USA) The greenish-blue material shown above is hyalite opal (SiO2·nH2O - hydrous silica). Hyalite is also known as glass opal. It is composed of opal-AN, which refers to amorphous opal having a network structure similar to silica glass, rather than opal consisting of silica gel spheres/colloids (most opal is the latter type). Locality: unrecorded site at or near Spruce Pine (but likely from the Chalk Mountain Mine), southeastern Mitchell County, western North Carolina, USA |
